Aim:
The present study was undertaken with the aim of evaluating the styloid
process in various TMD.
Materials and Methods: The study included 150 subjects, 50
subjects with Research Diagnostic Criteria (RDC/TMD) group I diagnosis,
50 subjects with group II diagnosis and 50 subjects without TMD as a
control group. Clinical examination followed by radiographic examination
using digital panoramic radiograph was carried out. The radiographs were
evaluated and analysed for the length and type of the styloid process.
Results: The mean length of the styloid process was 32.33 ± 4.14
mm in the RDC/TMD I group, 29.08 ± 5.26 mm in RDC/TMD II group and 29.94
± 7.02 in the control group. The length of the styloid process in RDC/TMD
I was higher followed by the control and RDC/TMD group II. The
difference between the groups was significant (p < 0.05). Styloid
process type II was the most predominant in the RDC/TMD I group,
followed by type I, and type III. In RDC/TMD II group, styloid process
type I was the most predominant, followed by type II, type III. Further,
in the control group, styloid process type I was the most prominent,
followed by type II and type III. A significant association between the
groups and the type of styloid process was found (p = 0.000).
Conclusion: Elongation of the styloid process is more
predominantly found in temporomandibular joint disorders RDC/TMD I
diagnoses than RDC/TMD II diagnoses. The study suggests evaluating the
styloid processes in TMD patients.
